在Android App中获取位置需要很长时间

Question

I was developing an android app for a while which used to access the current location of a user and then other things. But meanwhile the latitude and longitude return 0.0 & 0.0 and then after a while, it shows some values. I have had used FusedLocationAPI(currently deprecated) and FusedLocationProviderClient API too but got the same result as well. I used LocationManager but no improvements at all. I attached the current code down below. Could anyone show me a better way to access the location information? Thanks in advance :)

private void Locate() {
    locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
    if (ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION)
            != PackageManager.PERMISSION_GRANTED &&
            ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION)
                    != PackageManager.PERMISSION_GRANTED) {

        String[] permits = {
                Manifest.permission.ACCESS_FINE_LOCATION,
                Manifest.permission.ACCESS_COARSE_LOCATION};

        if (!PermissionsAs(this, permits)) {
            ActivityCompat.requestPermissions(this, permits, REQ_CODE);
        }
        return;
    } else if (ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION)
            == PackageManager.PERMISSION_GRANTED &&
            ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION)
                    == PackageManager.PERMISSION_GRANTED) {
        Location location = locationManager.getLastKnownLocation(LocationManager.NETWORK_PROVIDER);
        if (location != null) {
            double lattitude = location.getLatitude();
            double longitude = location.getLongitude();

            String string = getCompleteAddressString(lattitude, longitude);

            System.out.println(string);

            System.out.println("Longitude: " + String.valueOf(lattitude) + " Lattitude: " + String.valueOf(lattitude) + "\n");
            Toast.makeText(getApplicationContext(), "" + longitude + " " + lattitude, Toast.LENGTH_LONG).show();
            sendText(lattitude, longitude);
        }
    }
}

you could use this library, it handles the location providers automatically and give you the best possible location, I'm using it in my application as well and it works well. Location Provider Library
